error on esp-idf export.sh (Raspbery Pi OS 32bit)

[mshioji]

Hello,
I recently trying to setup Moddable SDK into new Raspberry Pi for educational purpose.
however, it seems installing esp-idf something goes wrong.

Installing Moddable SDK, it's OK. hello world works fine.
But after installing esp-idf for ESP32, when I hit “source $IDF_PATH/export.sh” I got following Warnings and Errors:

source $IDF_PATH/export.sh
Detecting the Python interpreter

• The warning said "tool was not found",
  but when I open esp-idf directly, it is not empty. It seems tools are installed correctly.

• Error message said "Please run '/home/oclpi/.local/share/esp32/esp-idf/install.sh' to install it.",
  but it doesn't solve the problem.

I've done many Moddable SDK installations and ESP32 device setups in the past, but this is the first time I've had this symptom.
Installation on Raspberry Pi was also not a problem before, so I wonder why...
Could anyone reproduce the same symptoms?

• Using Raspberry pi imager software to create a boot disk.
• Install Moddable SDK and esp-idf according to the Getting started document on github moddable SDK.
• after install esp-idf, hit "source $IDF_PATH/export.sh" .

I also tried with xs-dev.

• install nodejs and npm, then before install xs-dev, libudev-dev needed to install. then install ssh-askpass and xs-dev.
• Moddable SDK setup with "xs-dev setup --target-branch public"
• device setup with "xs-dev setup --device esp32", it seems instalation completed with no problem.
• however, when I open new terminal, same warnings and errors indicated.

I tried above twice, (2 manually, x2 xs-dev ) but four trials all failed. ><

Thank you,

Thank you for the detailed report. I haven't heard of this issue before your report. We'll try to reproduce it here.

Hello @mshioji,

I was able to reproduce your error if I skip step 8 of the linux install instructions:
https://www.moddable.com/documentation/devices/esp32#lin-instructions

8: Run the ESP-IDF install script. This will install the proper cross-compilation toolchain and utilities needed for the ESP-IDF build.

cd $IDF_PATH
./install.sh

Please do this step, then follow with source $IDF_PATH/export.sh.

Hello @mkellner and @phoddie,

Thank you for your quick reply.
Yes, actually I also thought that the step 8 solve the problem but the situation are the same.
The error message also recommended to run install.sh so I tried several times but the situation are the same.
This error is happened even if the install was made by xs-dev's automated process, I think it doesn't skip step 8.
I wonder what's going on.

I'd further try to separate an issue, then found something like this:

• on Raspberry Pi OS Bullseye "64bit", export.sh works fine. hello world on esp32 also works. (installed by xs-dev)
• however Raspberry Pi OS Bullseye 32bit still having a problem. tool was not found.

Now I found 64bit OS would be OK, therefore now it is no problem for my educational project.
however, 32bit version of Raspberry Pi OS is still recommended as a default on Raspberry Pi imager
so I little concern if the other people try to install it on 32bit OS and failed.

Thank you very much,

@mshioji – That's good progress. Great that you now have it working.

It looks like there are two options: switch to using the 64-bit installation or fix the issue on the 32-bit installation. That's for @mkellner to decide.

Hello @phoddie and @mkellner,
Thank you for the comment.
Yes, I will go with 64bit on my recent project so it's no problem. now it's not an urgent
but if you guys would consider continuing investigation, I also continue for this.

Thank you very much,
